Mini-excavators are below 5 tons, and 1.5-1.8 tons are the mainstream models. Small excavators below 15 tons, and 5-8 tons are the mainstream models. More than 35 tons are large excavators. The classification of large, medium and small excavators is based on tonnage. Generally, those below 20 tons belong to small excavators, those between 20 tons and 30 tons belong to medium-sized excavators, and those above 30 tons belong to the category of large excavators.
1. The standard of excavator weight
The weight of an excavator refers to the sum of its own weight and the weight of the load, generally in kilograms (kg) or tons (t). According to national standards and industry specifications, the weight of excavators is divided into the following grades:
The multiple range of excavators varies somewhat within each class.
1. Small excavator: generally between 1-5 tons, less than 6 tons.
2. Medium-sized excavator: The weight is between 6-20 tons, and the most common one is a 13-ton medium-sized excavator.
3. Large excavator: the weight is between 20-50 tons, and the more common ones are 21 tons, 30 tons and 45 tons.
4. Super large excavator: the weight exceeds 50 tons, and the weight of the largest excavator can reach more than 1,000 tons.
2. Factors affecting the weight of excavators
The weight of the excavator is the key factor affecting its total weight, and the following factors will also affect the weight of the excavator:
1. Model and size: Different models and sizes of excavators have different weights.
2. Configuration and accessories: The configuration of the excavator and the number of accessories equipped will also affect its weight.
3. Working environment: In different working environments, the weight of the excavator will be different.
4. Material and structure: The material and structure of different excavators will also affect its weight.
In short, the weight of the excavator is a very important indicator, and it needs to be selected according to the specific situation when purchasing or using the excavator. At the same time, it is necessary to pay attention to the relevant safety regulations when using and maintaining the excavator to ensure the safety and smooth progress of the work.
The three most important parameters of an excavator are: operating weight (mass), engine power and bucket capacity.
The definition of a small excavator is that a backhoe loader of 1 to 6 tons can be called a small excavator, and products of 2.7 to 3.0 tons account for a relatively large proportion because they can be easily carried out by general-purpose transport vehicles. ground transition.
Extended information:
When the excavator unloads the soil, it must not rely on the action of opening the bucket to pour out the soil, but at the same time of opening the bucket, use the stick to instantly recover and then open it to throw the soil out, which is faster! When the excavator is leveling the ground, there is a trigonometric relationship between the operation of the boom and the stick.
That is to say, the extended length value of the arm cylinder needs to correspond to a number of the extended or retracted boom cylinder, so as to control the bucket to keep moving in a straight line and to trim the ground. It is worth noting that in daily work, excavator leveling the ground is a job that requires careful observation and patient operation.
